he used to load us onto an rv and drive us around the country to show us how great this nation is. he would tell us history of our country even if he didn't know it. we would ask him questions when we were driving through arizona. "grand-dad, why do they call this town yuma, arizona?" and he would say, "well, let me see, that's because when this town was founded, there was a gun fight and one guy shot the other and he grabbed his heart and said, 'you ma' and then died." [laughter] i talked to my grandfather all the time about this country. he tells me that, son, this country, we forget we talk always about the declaration of independence. but really, this nation was founded on a declaration of interdependence -- this recognition that we need each other. when i talk to my grandfather now, i anguish to him that we are a nation that has become so polarized, where people are so quick to identify themselves as democrat or republican before they say, first and foremost, that i am an american. they're so focused on left and right that they forget that this nation must go forward.
